Grammatical Change to Flea Market

Oooops. Forgot about this...Under the wiki page flea market I made a grammatical change to the line....The car boot sale is similar to a flea market, however is more popular in the United Kingdom. Prior to my change it said but is more popular. But certainly shouldn't be used in this situation. It sounds a littly awkward and isn't grammatically correct. Very small change, I know, but every little counts.
